The latest version of Chrome (35) stopped supporting SDES and now requires dtls-srtp.  So now, I need to configure my FreeSWITCH to work with dtls-srtp.

I see that my installation has dtls-srtp.crt and key files under /usr/local/freeswitch/certs/ but I could not find much info on how to enable it.

Do I need to replace these with my own generated keys?

Where in the config do I specify what directory the keys are in?

To complicate things I am on FS  1.5.6b from about 8 months ago.  It should have dtls-srtp support though, right?

This is a fairly urgent matter for us - we dropped the ball and did not catch this change in time - and I'd be happy to consider commercial support from the FS team if available.  If so, please contact me via email directly.
